Recently I observed that ETL was taking a very long time. Upon analysis I found out that STEP: PLP_APXACTSGROUPACCOUNT_A1_LOAD that was previously completed in 17-18 mins, is been running for 5-6 hrs and there was hardly anything processing happening on data warehouse side.
It seems to happening only in version 22.214.171.124 and 126.96.36.199 and does not have any impact on 7.9.6 or 188.8.131.52

Objects : Indices W_AP_XCT_GAD_D_F11 and W_AP_XCT_GAD_D_F6.
Modification: Change the Index Usage for these indices from
